Add an ExtraLabels map[string]string field to the Loki Config struct so
users can define static key=value labels that are merged into the stream
labels of every log line sent to Loki. This allows users to distinguish
streams (e.g., by environment or datacenter) without hardcoding values.
Built-in dynamic labels (application, site_name, source, etc.) always
take precedence over extra labels to preserve existing behavior.
Example config (TOML):
[loki.extra_labels]
environment = "production"
datacenter = "us-east-1"

Add new save_syslog config option to collect events from the v2 UniFi
system-log API (/v2/api/site/{site}/system-log/all).
Changes:
- Add SaveSyslog field to Controller struct
- Add collectSyslog() function using v2 API
- Keep collectEvents() using v1 API for backwards compatibility
- Add RedactIPPII() helper for PII redaction
- Update lokiunifi to log raw JSON (parseable with Loki | json)
- Reduce indexed labels to low-cardinality fields only
- Add SystemLogEntry handler in lokiunifi report
Config: save_syslog (v2 API) vs save_events (v1 API)
Env: UP_UNIFI_DEFAULT_SAVE_SYSLOG=true
